Russet: Private on-device AI

Private, powerful, personal

Free

Russet enables private on-device AI on Mac, powered by the latest and greatest models. By default, chats run fully on-device with no accounts, no ads, and no tracking of messages. Russet's models are optimized for Apple hardware and downloadable, so they work completely offline. All in one clean, native interface designed for privacy, focus, and flow. Features • Flexible chats: Choose models, adjust response style, branch or lock chats, and analyze PDFs and images. • Text-to-speech: Generate speeches in custom voices from your input text to save and share with Russet for iPhone and iPad. • Agent: Work with health data, schedules, contacts, and files through system-aware automation. • Flow: Summarize, rewrite, debate, label, and translate text, even offline. • Intelligent Templates: Get instant briefings powered by your calendar. • Local Inference Server: Expose Russet's loaded MLX or GGUF model via an API at localhost, so other apps and tools can use it without loading another model. • Offline-ready: Works without an internet connection. • Multilingual: Supports 13 written and spoken languages.
